Kherebt Jbarah Village

 قال رسول الله (ص):}تخللوا فإنه من النظافة، والنظافة من الإيمان، والإيمان وصاحبه في الجنة{  This project include design water and wastewater network system by using waterCad and sewerCad. Water is the grace of our god to us , there is no place to go expect there is water in that . Living without water is unimaginable. The lack of water will lead life to the death . In fact, it is very hard for plants, animals, and especially humans to live without. General Introduction :  

There is many historical sources of water in Palestine the Jordan river and surface water and ground water but I say historical because of many problems faces this sources , and these problem are : There is an errors in saving water that reflect our culture .Lacks in water in last few years because of greenhouse effect .

Our project aims to design water and wastewater distribution system network of Kherbet Jbarah Village in Tulkarem governorate in Palestine. The study will be utilized in designing the water and wastewater distribution network to be able to meet the demand of water and create a healthy environment for Kherbet Jbarah Village people with their available resources . Objectives

Groundwater is utilized through wells. Ground water is a very important source of water in Palestine as it represents 100% of the fresh water in the country. Ground Water :

The most important source of water is the rain which feeds the other sources and completes it. In general the amount of rain in Palestine different from one year to another, so rainfall can not be a reliable source for all aspects of our daily life. Surface Water (Rainfall and Jordan River)

Only a fraction of this can be used by Palestinians in the especially in West Bank. Israel has remove Palestinians access to the entire Lower Jordan River .  Jordan River :

Sources of WastewaterDomestic Effluents: The so-called sewage water which is used in domestic units or public buildings. Industrial Effluents: The waste resulting from the use of water in the different manufacturing processes, these wastes may contain toxic materials or harmful to plants that are linked to a network of discharge after achieving certain conditions.

Infiltration : water which enters the sewers from the surface through flaws and defects in the system. Storm water : Modern networks are separated rainwater for other residues 

Kherebt Jbarah village is located south of the city of Tulkarem after 6 km, inside the barrier. and the population of the village is about 300 capita . This decision was due to the challenges people from this village are facing, in terms of an old agricultural water network and the lack of a wastewater network . Study Area

Data Needed to Design a Network In order to design a new water and wastewater network system we should have various types of data , and these data include :Consumption rate,Plans for new network, Geographical maps of the area,and Places of industrial and commercial areas.

Maintenance of Wastewater Conduit Wastewater networks system need regular maintenance to achieve its goal. Maintenance can be achieved by these ways :Water pumps Air pumps Chemical solutions

Stages of Wastewater TreatmentMechanical Stage : Separating the solids from the liquid wastewaterChemical Stage : Transformation of dissolved organic matter in the water to solids graduallySedimentation Stage : After the organic matter transform to greater size this will lead these matter to free fall (sedimentation) by slow velocity and without mixing

Uses of Treated Water: Treated wastewater can be used in several purposes either directly or in-directly. In general, the percentage of re-use of treated water by various sectors represented in the following: Agricultural purposes 60% Industrial purposes 30% Other purposes, e.g. feeding the groundwater 10%

Climate In Tulkarem The climate is described as hot dry in the summer and moderately warm and rainy in winter.

The annual mean rainfall is 645 mm. About 80% of the total precipitation falls between December and March while June, July and August are totally dry. Rainfall in Tulkarem

Evaporation In Tulkarem Potential evaporation rate is particularly high in summer as it can reach about 200mm /month in July. Evaporation in winter is about 45 mm/month in December. During spring and autumn, the potential evaporation reaches about 90-135mm/month.  

Humidity In Tulkarem Relative humidity during May reaches approx 60% and it can reach 35% in Khamaseen period.

Expected Outcome The expected outcome of this project is a wastewater network system and calculate B.O.Q for this project . 

Methodology To make a project you have to do many steps these steps conclude in five levels :choosing the study area : We chose Kherbet Jbarah as our study area to design the water supply and wastewater network. This decision was due to the challenges people from this village are facing, in terms of an old agricultural water network and the lack of a wastewater network.

Data Collection We collected data that include: the population , growth rate ,water consumption per capita , return wastewater factor , …..etc .

AssumptionsWe assumed that in each house we have 4 persons .Assume that the return flow equal 80% .the maximum hourly factor equal 3.Infiltration rate equal 20%

Selection of the software We selected WaterCAD software to design .There are many available to work on it but we select WaterCad because of its capabilities and because we are more familiar with. Other options might be :Pipe Flow Expert v1.08 .Bentley auto pipe plus .EPAnet .WaterCAD :

WaterCAD is a software by which we can conduct design and analyze water distribution network and we using the program according to the Palestinian standard and specification. WaterCAD

SewerCAD SewerCAD can be used to model both pressurized force mains and gravity hydraulics with ease, by using steady-state analysis with various standard peaking factors and extended-period simulations.

SewerCAD is an easy-to-use sanitary sewer modeling and design software product that thousands of municipalities, utilities, and engineering firms around the world trust to design, analyze, and plan wastewater collection systems. Engineers can model both pressurized force mains and gravity hydraulics with ease, using steady-state analysis with various standard peaking factors, and extended-period simulations.

Designing the network Sewer systems shall be designed to convey wastewater discharges from domestic , commercial and industrial premises to the point of treatment without prejudice to health and safety. Such design should also include allowances for future growth and for extraneous discharges up to such flow that will justify rehabilitation.

The following factors inter alia must be taken into consideration in the assessment of the sewerage system most appropriate for a particular area:  The nature of the area and the prevailing climatic conditionsExisting wastewater systems within the defined areaThe degree of pollution in the surface water and pipe depositsThe risk of leakageThe nature of the recipientGeology, ground conditions, topography, etc.Economic considerations

Wastewater Network System In the sewer network we found that all of conduits velocity lie between the design constraints Also we found that all of the conduits have the slope within the design constraints and the conduits have the cover which lie between the minimum and the maximum constraints.

We recommended going ahead with this project as soon as possible since this village suffers from the sewer problems and suffering from the lack of water, so this village really need to it. Also we can make combined system ( wastewater and storm water ) but we choose this system because of small area and the slop of this area make two separate system more easily .
